FILLING-REPLEN'ISHIN G LOOIllI.

Be it known that I, EDWARD S. STIMPSON, a citizen of the United States, and resident of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improve- -ment in Filling Replenishing Looms, of which the following description, in connection with the accompanying'drawing, is a .pecificatl on, hkecharacters on the drawing representing like parts.

- This invention relates to looms provided with mechanism to-replenish automatically the filllng 1n the WOl'klIl" or running shuttle, andit has for its b]ect the production of meansfor so controlling the filling end i of a fresh supply of filling that the shuttlethreading device will assume control of'the "fresh filling at about the time the shuttle is leaving the shuttle-box at the replenishing side of the loom.

In looms of thisgeneral type it is common to provide a temple thread-cutter to cut the fresh or new filling at the selva e of the cloth nearer the replenishing site of the loom after such filling hasbeen beaten in,

v and in order that the length of filling leading from the selvage to the end-holder on tlie' filling-feeder or magazine shall clear the shuttle-box before the temple threadcutter operates I have given apeculiar const-ructionto the. means for controlling the filling thread as the replenished shuttle moves outof the box.

ward the ti 5 extension o the shield prevents the filling- My present invention is more especially adapted for use on looms in which shuttles from drawing over behlnd the apex, ant thence off the beak, on thesecond pick of "the shuttle after replenishment, and the shield'performs such function perfectl ,but

in running the, loom at hi h'speed the rent- I ward extension of the shleld sometlrnes dey lays the prompt threadin of the shuttle.

thereby to hold the filling'in alinement substantiall "with the longitudinal axis of the shuttle, at such an arrangement holds the filling so far back toward the rear side of the shuttle that it cannot pass under the frontwardly extended shield, in my patented structure referred to, and the shuttle will fail to thread. To overcome the objections mentioned I have mounted on the front wall of the replenishing shuttle-box a thread-engag,

ing device or controller, which engages the fresh filling-end as the lay moves bacl replenishment of filling has been effected, so that the filling leads from the bobbin in the shuttle to a point on the front wall of the box. Thus the thread of filling lies in a path which is at a small angle to the lon itudinal axis of the shuttle and such that t e filling is yet held toward the front of the box so that it cannot lie upon theto of the shield forming a part of the threa in device. Consequently, when the s'hutt e is picked the thread of filling willbe held in such position that it draws across the beak and beneath the front edge of the shield "just before the threading end of the shuttle leaves the box, and consequently, as the shuttle continues its flight the thread is surely and positively carried down and under the beak by the action of the front and forward edges of the shield, so that the thrading device assumes the desired control "of the filling thread. As will appear hereinafter this thread engaging device or controller is so constructed that on the Second backward stroke of the lay after replenishment the len h of filling between the selvage of the 0 0th and thefilling-feeder will be shed or disengaged automatically from the controlleryto drop outside the shuttle-box after the temple thread-cutter operates.

The novel features of my inventlo will I after- Specification of Letters Patent. Patented Mar. 29, .1910. I

Application filed October 23, 1909. Serial No. 524,173.

be fully described in the subjoined specifi cation and particularly pointed out in the following claims.

Figure 1 is a top plan view of suliicient portion of an automatic filling replenishing loom with my invention applied thereto, the shuttle having just received a fresh supply of filling; Fig. 2 is a view similar to Fig. 1, but omitting the replenishing mechanism, and showing the filling end engaged by the controller as the lay moves back, the shuttle being shown as just about to leave the replenishing shuttle-box; F ig. 3 is a right hand end elevation of some of the parts shown in Fig. 1; Fig. i is a front elevation of the front wall of the replenishing shuttle-box, with my novel thread engaging device orcontroll'er thereon.

Referring to Fig. 1 the lay A, picker B for moving the shuttle through the shed, the shuttle-box C having a front wall D,

and mechanism to replenish automatically the shuttle with filling, comprising the rotatablefilling-feeder or magazine E, F. shown in full and dotted lines, Fig. 1, thetransferrer G and its adjuncts, the end-holder carried by or forming apart of the feeder and consisting of a bell-shaped member or disk H and central stud I, and the breastbeam J on which the replenishing mechanism is mounted, may be and are all of usual construction and operation and familiar to thoseskilled in the art. In such apparatus the filling ends are led from the reserve filling-carriers or bobbins mounted in the feeder to the stud I and around the notched periphery of the disk'H, the feeder herein illustrate d being of the well known rotary type, and when a filling-carrier is inserted in the shuttle by the transferrerthe filling end leads from such carrier outward under the disk H and up to the stud I, which is coaxial with the feeder, so that as the shut- ,tle may not assume control of the filling thread until nearly at the end of its shot, and sometimes not then, resulting in thread breakage on the next pick. In some cases this fault may be corrected by providing. a

guide on the lay extended rearward over the top of the replenishing shuttle-box, to

' engage the filling thread as the lay swings back after replenishment and hold the thread substantially in .alinement with the longitudinal axis of the receding shuttle. Such an arrangement is of no value, however, when the shuttle is provided with a threading device having the shield extended frontward beyond the apex of the beak, as in my patent hereinbefore referred to, or in other patents granted to me at the same time, Nos. 933,728 and 983,729,for the centrally held filling thread. is prevented from passing under the front edge-of the shieldto be thereby depressed and carried beneath the beak.

I In my present invention I have devised a thread engaging device or controller whibh coiiperates with the filling end as the lay swings back after replenislnnent and causes the filling end to lead to the shuttle from a point on the front wall of the'box near its outer end, at a small angle to the longitudinal axis of the shuttle and so positioned that the filling thread will pass under the front edge of the shield just before the shuttle leaves the box.

In F l and 2 the shuttle K is shown as provided with a threading device which includes the beak rearwardly extended over the outer end of the thread passage and the shield 57 frontwardly extended and overlapping the beak and having its front edge at a considerable distance beyond the. apex of the beak, substantially as in-my patents referred to.

Upon the top of the front box-wall D, I provide a thread engaging device or controller, shown in the oresent einbodiment'of my invention as an elongated, longitudinally extended lip 1v upturned from the top of the box-wall and rearwardlv inclined, the upper edge 2 of such lip gradually rising from the top of the wall, at 3, to its outer, upper corner, at at, and the outer end 5 of the lip is not only inclined rearward, as shown in Fig. 3, but it-is also inclined out-- wardly, as shown in Fig. i, the corner 4 being slightly rounded, as shown. In practice this thread engaging lip or controller is conveniently made as a part'=of the boxwall casting, and in front-elevation the lip is triangular in. shape, its base being parallel to the inner or'rear face of the wall D,

but by treason of the upward and rearward inclination of the lip as a whole its upper edge 2 is diagonally extended, as clearly shown in Figs. 1 and 2, the lip overhanging the top of the wall D but it does not project over the top of the shuttle-box, as will be apparent.

Referring to Fig. 1 the shuttle ii has just been provided with a fresh filling-carrier or bobbin L, and the filling end M leads therefrom in a diagonal direction upward and rearward tothedisk H and thence to the stud I, Figs. 1 and 3. As thelay moves back and the transferrer G rises the feeder is rotated in the direction of the arrow,F1g. 3, to move the next filling-carrier to transferring posiaround "its outerjend 5, as shown in Fi "as the pick of the shuttle begins. The shut tlecontinues-its movement, and just before it leaves thi box C the filling thread is positioned by the controller as shown in Fig. 2, at a smallangle to the longitudinal axis of the shuttle and across the exposed portion of the beak in such position with relation to the shield b that its front edge ositively engagesaiid depresses the thread elow the .beak, practically before the eye-end of the shuttle leaves the shuttle-box. 'There is no interference with the movement of the picker, the top of the'yshuttle-box is wholly clear and open, and as'the lay continues its backward movement the thread of filling continues to lead from a fixed point, to wit, the notch or recess fol-med by the'top of the boxwall and the outer edge 5 of the thread controllein. By inclining the edge 5 the thread is-drawn down surely and positively into 'th'e'notch, so'that there is no danger of its escape prematurely, and the rearward inclination or overhang of said controller as a whole serves to. still further insure the engagement-and holding of the filling thread.

. complete threading of the shuttle is inevitiVVhentl ie thread is carried down and under the beak of the threading device the able on the return I pick of the shuttle, as will be understood y those familiar with this class-of apparatus, and it will be manifest that-if the filling end should be permitted to assume the broken line position M, Fig. 2, itwould without the use ofv the thread controller) the control of the thread by the threading'device on the shuttle must inevitably be retarded until the shuttle is well on its way toward the non-replenishing explained, and after boxing of the shuttle at the opposite side of the-loom the filling just laid is beaten in, and as the lay moves frontward the filling will extend from the right-hand selvage of the cloth to the end= holding means'on the filling-feeder, to be cut at the salvage by the usual tem le thread-cutter. It is now necessary that t e length of filling leading from the selvage to the end-holding means he disengaged or cleared from the thread-controller 1 before it is cut at the selvage, in order that'the cut end may not lie in the shuttle-box C, and

the secondary function of the controller is to clear itself of the length of filling referred to.

When the first pick of fresh filling is beaten in the shuttle is at the left-hand side of the loom, and the beating in causes the specified pick to be held in the cloth. so that as the lay moves back after the beat-up the slack length of filling leading to the right from the selvage of the cloth will travel across the top of the box-wall D and as the lay continues to recedc such filling slides up the inclined upper edge 2 of the controller and is shed therefrom over its corner 4.

i This length of filling is thereby cleared or shed from the thread controller, it hangs between the cloth and the end-holding means in front of the lay, and when out at the selvage drops down and trails from the stud I, out of the way of the'shuttle, picker, and lay, and hence cannot be caught in the shuttle-box or caused to foul the shuttle or the running filling. Thus by a very simple device I cause the shuttle to assume prompt control of the fresh filling before the shuttle leaves the shuttle-box after replenishment, and I clear the filling-end automatically from the thread controller, shuttle-box, shuttle, and other parts of the mechanism before the temple thread-cutter serves the fillingend at the selvage of the cloth.

Having fully described my inveuti'omwhat I claim as new and desire to secure by Letters Patent is y 1.
